WINDOW-SCREEN FRAME.

SPECIFICATION forming part of Letters )Patent No. 445,026, dated January20, 1891.

Application filed October 6, 1890.

To @ZZ wwm it may concern.'

Be it known that I, JUDsoN B. PHILLIPS, a citizen of the United States,residing at Fenton, in the county of Genesee and State of Michigan, haveinvented certain new and useful Improvements in Vindow-Screen Frames, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to new and useful improvements in framesespecially adapted for window-screens; and the object of my inventionis, to construct the frame so that it can be readily manufactured andshipped in a knockdown condition, which dispenses with the use 0f anytool for putting it together, and which at the same time may be readilyaltered to any desired size within the length of the bars composing itand without requiring any skill or any other tool than a common saw.

To this end my invention consists, principally, in the construction ofthe bars composing the frame, all as more fully hereinafter described.

In the drawings which accompany this speciiication, Figure 1 is aperspective View of my improved frame as preferably constructed for useas a window-screen frame. Fig. 2 is an elevation of my improved framewith one corner thereof shown in vertical central section in the planeof the frame. Fig. J is a cross-section on the line x 0c of Fig. 2. Fig.4 is a perspective view of one of the bars forming the frame.

A are the bars composing the frame, each bar being provided with squareends and with a tenon B, preferably formed integral with the bar, on oneside thereof. This tenon extends the whole length of the bar, except atone end of the bar, where the bar extends beyond the tenon a distancepreferably equal to the width of the whole bar. In manufacturing the barthis is preferably accomplished by forming the tenon the whole length ofthe bar and then cutting away the specified portion of the tenon. Incross-section this tenon is preferably made of dovetail or T-head shape,as shown.

C are corner-pieces adapted to engage with the tenons of the bars bymeans of suitable Serial No. 367,259. (No model.)

mortiscs formed in the right-angled sides of the cornerpieces.Preferably I construct these corn er-pieces of triangular-shaped piecesof wood having a thickness equal to the thickness of the bars, and, ifdesired, of more or less ornamental form.

My frame is constructed of four of the bars and of four of thecorner-pieces described in the manner shown in the drawings, in whicheach bar is shown with one end abutting against the side of one of theadjoining bars, while the other end, on which the tenon is partly outaway, is shown to overlap the end of the other adjoining bar, all thebars being arranged in like manner and united together by means of thecorner-pieces, which engage with the tenons of two adjoining bars. Themanner of accomplishing this is obviously simple and need not bedescribed. W'hen the bars are so joined, it will be seen that while eachbar at one end overlaps the end of one of the adjoining bars its tenonoverlaps the end of the tenon ot' the other adjoining bar. The result ofthis arrangement is that each bar is thereby held against longitudinaldisplacement in either direction, and also against displacement ateither end in the direction of the adjoining bars. Thus if a fabric cutto iit the opening of the frame between the bars and corner-pieces issecured therein by securing the edges of the fabric to the tenons thewhole frame becomes rigid, and if a fabric or material of greaterrigidity than the ordinary wire screen is desired to be secured in theframe the corner-pieces may be even omitted, if desired.

For window-screen frames I preferably pi'ovide two of the bars withtenons D upon their outer faces, whereby the frame may be secured invertical guides on the window-frame in the well-known manner forpermitting the screens to be adjusted up or down in the window.

With proper workmanship a frame of my construction is so rigidly heldtogether by the corner-pieces that even without the help of the fabricsecured Within the frame it will maintain its form against anyaccidental displacement, so that the use of nails or screws is entirelysuperfiuous, thus permitting the parts of the frame to be readily takenapart IOO again, and, if desired, to be altered in size. In Order to doa minimum of Workin altering the size 'of the frame, the cutting off orshortening of the bars is accomplished by sawing oft the requiredportion on that end of the bar on which the tenon extends to the end ot'the bar, thus saving the work of readj Listing the other end of the bar,which is maintained the same for any desired size of frame.

To determine the proper length of the bars to obtain a frame of givensize is obviously not a difficult matter and need not be eX- plained.

The great advantage of my frame is that it may be manufactured andshipped in a knockdown condition, and when accompanied with simpleinstructions may be put together by any one endowed with commonintelligence and without requiring any other tools than a handsaw forsawing the bars the proper length.

I am aware that frames have been constructed heretofore of four barsoverlapping each other at the corners in like manner as shown in myframe; but in all such constructions the bars were never united withoutthe use oit' screws or nails and without the help of the fabric intendedto be secured within the frame.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A frame composedof four like bars provided with tenons upon theirinner sides and corner-pieces engaging the tenons of two adjoining bars,each bar extending at one end beyond its tenon and overlapping with saidend the end of one of its adjoining bars in like manner in all the barscomposing the frame, substantially as described.

2. A frame composed of four like bars provided With tenons upon theirinner sides and corner-pieces lengaging the tenons of two adjoiningbars, each bar extending at one end beyond its tenon to a distance equalto the width of the bar and overlapping with said end the end of one ofits adjoining bars in like manner in all the bars composing' the frame,substantially as described.

3. A knockdown frame comprisingr four like bars, each formed on one sidewith a tenon cut away near one end of the bar equal to the widthof thebar, whereby said bars may be arranged to form a frame in which each baroverlaps the end of one adjoining bar and its tenon overlaps the tenonof the other adjoining bar in like manner' in all the bars, subvstantially as described.

4. A knockdown. frame com-posed of four like bars, eachv formed on itsinner side witha T`-l1ead tenon cutaway near one end of the bar and offour triangular corner-pieces having two rectangular sides providedqwithniortises adapted to engage the tenons of the bars, said bars beingadapted to be arranged into a frame in which each bar overlaps the endof .IUDSON B.
